SPECIFICATION forming part of Letters Patent No, 580,505, dated December11, 1894.

Application tied November 15,1893. serial No. 491,014. (No man.)

To all whom it may concern:

Be it known that we, RICHARD CLARK and LOUIS M. OROM, citizens oftheUnited States, residing at Warsaw, in the county of Coshocton and Stateof Ohio, have invented a new and useful Printing-Press, of which thefollowing is a specification. i Our invention relates to improvements inprinting presses, and to that particular* class thereof employing astationary type-bedand a traveling impression cylinder arrangedthereover.

The objects of our invention areto provide a press of of the aboveclass, the samebeing so arranged as to readily receive and automaticallyemit or discharge the paper after-,printing and whose capacity for rapidprintingis increased. Various other objects and advantages of theinvention Will appear in the following description and the novelfeatures thereof will be particularly pointed out in the claims.

Referring to the drawingsz-Figure l is a plan view of a pressembodyingjourlinvention. Fig. 2 is a side elevation thereof;` jfFig. 3is a vertical longitudinal centralsectionalview. Fig. 4 is a transversevertical sectional- View. Fig. 5 is `an enlarged view in crosssection ofthe revolving cylinder. Fig. 6 is an enlarged detail in perspective ofthe carriage for conveying the cylinder.

Like numerals of reference indicate like parts in all the iigures of thedrawings.

In the practice of our invention we employ any suitable bed-frame. Inthe present instance, however, We have illustrated one simple formthereof. In the construction shown We employ a pair of lower basesills1, from which rise standards 2 that support the longitudinally disposedupper sills 3, the sides of the vframe being connected by suitablecrossbars or beams 4. The sills 3 constitute a track and are provided attheir outer sides with cleats or Iianges 5, Whose upper edges are abovethe sills to retain the cylinder carrying carriage, hereinafterdescribed, thereon. Arranged upon the frame thus constructed isthecylinder carrying carriage, and

i1 the same consists of opposite sides 6, which are reduced toward theirends, and isof a width to fit within the cleats 5. Rollers 7 are locatedat the four corners of the carriage andare designed to move upon thetrack,

cheap and simpleconstruction and which as before stated, is formed bythe upper sills 3. `The sides `6 are at their centers provided withbearings 8, in which are jour-` naled the ends of a transverseshaft 9which accommodates and passes through the im-` its surface covered withany desired covering,

as shown. A l Standards 1.1 rise from `the sides 6 ofthe cylindercarrying frame, and at their upper ends are provided with slotted lugs12 in which are loosely mounted the opposite eX- tremities of the axis`13 of a paper-grasping roll 14. Inasmnch as the lugs 12 are slotted, ll it Willbe seen that the roll 14 mayraise and lower, but ordinarilyruns in surface contact with thecylinder 10 by which it is revolved. `Atopposite sides of the cylinderwe mount `pression cylinder l0. Thiscylinder 10 has upon the sides 6 the transverse guard-bars 15,

and the same are provided `at intervals with yielding substantially`triangular` guard-fingers 16, which are curved at their inner sides toembrace the opposite sides of the cylinder, as best shown inFigs. 5 and6. Below these l guard-bars in bearings 17 ateach sideof the cylinderl0, We journal loosely a pair of inking-rolls 18, `whose lowerfsurfacesare-in .the same plane as that of the cylinder 10. Above `the inkfrollswe journal at each side of the cylinder 10, in bearings 19, the axles ofa gnide-roll 20.

Hinged leaves 21 are arranged'upon the ends of the cylinder-carryingframe, and are disposed normally inward toward the cylinder thereof,being supported at their inner ,l endsby cross bars 22 which span theframe at each side of the cylinder, and complete iiies on which theprinted sheets are allowed to accumulate.

Opposite superimposed frames 23 are horizontally disposed above theopposite ends of the framework of the press, and these frames supportinclined feed-tables 24 which decline from their outer ends toward theirinner endsl and have extended in front of such ends the4 substantiallyhorizontal extensions or plates 24a. Each feedtable is provided ,atopposite sides or ends with arms 25 that are inwardly disposed andconnected at their inner ends and have upturned cam or hook-shaped ends26. Each frame 23 comprises in its make-up a cross-bar 27, and to eachcross-bar is attache'd a pair of coiled springs 28. Pairs of IOO tapes29 are connected at their extremities to the inner ends of thesecoiled-springs, pass over and around the rolls 20, and are connectedthereto. The rolls 20 are connected by intermediate guidetapes 30 whichare wound reversely thereon so that the rolls revolving in the samedirection will cause the tapes to wind upon one of them and unwind fromits companion.

At the center of the framework we locate in the cross-bars 4 of thebed-frame vertical adjusting-screws 31 whose lower ends are so shaped asto receive a wrench. The upper ends of these screws are swiveled to theunder side of the type-bed 32. At each side of the type-bed andsupported bycleats 33 We locate inking-tables 34 which are in a planewith the type-bed. Paper-receiving tables 35 occupy the ends of theframework below the frames 23.

Any means may be .provided for reciprocating the cylinder-carryingcarriage over the type-bed. In the present instance, however, We haveillustrated one form which we will proceed to describe. We locate intransversely opposite pairs of bearings 36 crankshafts 37, connectingthe two by means of an intermediate rod 38a. Both ends of one of thecrank-shafts 37 are extended to form rock-arms 38, which by means oflinks 39, shown in Figs. 1 and 2, are loosely connected with theextended ends of the shaft 9 of the impression cylinder. The remainingshaft 36 has one or both of its ends extended, and is designed to serveas a handle 39L where the press is operated by hand, or to be connectedwith any suitable motor for vibrating the same.

A pair of hangers 40 depend from the opposite sides of each of thefeed-tables, and being provided with bearings accommodate a transverseshaft 42 located under each of said tables. The intermediate portion ofeach shaft is upwardly cranked,as at 43, and passes through an elongatedslot 44 to a point above the base 23 of each feed-table. One of theouter ends of each shaft 42 declines toward the center of the machineforming an arm 45, the extremity of which is inclined or slightlyupwardly bent as at 46 and arranged in the path of the journal 9 of thecylinder. The opposite sides of the inclined feed-tables .24 areslotted, as at 47, and in the same there are mounted for movementtransversely disposed slide-bars 48, which at their centers areconnected to and adapted to be actuated in one direction by the crankportions 43 of the shafts 42. It is to the end of these slide-bars 48that the arms 25 are connected.

In the operation, the paper is fed by attendants from the inclinedfeed-tables 24to points over the edges of the extensions 24a. Thecylinder-carriage advances toward the projecting paper, and the journal9 which projects beyond the arm 39 thereof strikes the inclined end 46of the adjacent arm 45, causing the same to elevate and hence rock theshaft 41. This action of the shaft 4l allows the arms 25 to recede inadvance of the approaching cylinder until it has reached the limit ofits backward movement. In the meantime, the paper-grasping roll 14 hasarrived in contact with the cam ends 26 of said arms 25, so that as willbe obvious, the roll 14 iscaused to rise and hence passes over the endof the paper on the plate or table extension 24a. As the carriagerecedes the paperroll 14 travels down the cam ends 26 of the arms 25 andengages with the paper, clamping it upon the revolving cylinder. TheWeight of the arms 45 is sufficient to return the parts to their normalposition.v The cylinder, it will be observed, is revolved in that itruns in contact with the track 3, and the tapes 30 move under thecylinder in the same direction as the travel of the latter, so that thesheet of paper engaged by the papergrasping roll 14 is fed to thefingers of the cylinder and continues under the fingers until it arrivesin contact with the guide-tapes, which continue the movement of thepaper and carry the same under the cylinder to the opposite sidethereof. Of course when the paper arrives under the cylinder it is incontact with the type, so that an impression is made upon one side ofthe paper. At this point the guide-tapes 30 conduct the paper from underthe cylinder and deliver it upon the leaves 21. By this time thecarriage is at the opposite en d of the machine, Where the operationdescribed is repeated, and in moving from thispoint to the startingpoint the second sheet is printed and delivered. At intervals when anumber of sheets have accumulated the leaves 21 are reversed and dumpthe contents upon the tables at the ends of the machine. Theinking-rolls, it Will be seen, travel over the ink-tables 34 and servetosupply the face of the type with the necessary ink. The coiled springs28 give tension to the tapes 29 and serve to revolve the guiderolls 20,and aid in the operation of the guidetapes 30.

It will thus be seen that we have provided a machine adapted to rapidlyprint and automatically feed or carry through the press the successivesheets of paper, the said machine being of cheap and simpleconstruction, comprising few parts, and those of simple formation.

We do not limit our invention to the precise details of constructionherein shown and described, but hold that we may vary the same to anydegree and extent within the knowledge of the skilled mechanic. At thispoint further attention is directed to the manner of feeding theunprinted sheets from the opposite feed tables to the impressioncylinder. It has already been noted that the operator or feedermanipulates the unprinted sheets on the tables 24 so as to bring theedges of the same over or slightly beyond the edges of the tableextensions or plates 24., and toward the approaching impressioncylinder. When IOO IIO

the impression cylinder approaches the sheet of paper thus positioned,the paper roll `14, engages with the upturned cam or hook shaped ends 26of the movable arms 25 at that end of the machine, and the shape ofthese ends willcause the roller 14 to raise above the paper, which isheld by the feeder, and to pass to a position over the extensions orplates 24a. .I ust before thishas taken place the arm toward which thecylinder has approached has been lifted by the engagement of one end ofthe journal 9, therewith, so as to move the upwardly disposed crankportion 43, of the shaft 42 in a direction which relieves the weight ofthe arm 45from the slide bar 48 connecting one end of the-arms 25, sothat there Will-be nothing to interfere with the paper roll 14, carriedby the carriage, from pushing the arms 25 in front of the same, as itrises up the cam ends 26, this movement being necessary to carry thepaper roll above the sheet of paper and back from the edge thereof.` Asthe impression cylinder commences to retreat from the feeding table,

which has just been referred to, the paperv roll 14 travels down the camends 26 of the arms 25, and rolls `over the sheetV of paper, which willnot move until the said roller reaches the edge of the feed table or atleast the extension 24a, thereof, at which time the friction of thesmall roller on the cylinder will cause the paper to be rolled betweenthe roller and cylinder and moved under the guides at one side of thecylinder, until caught by the tapes passing under the cylinder, andsince the carriage is during this time moving toward the opposite feedtable, an impression will be made on the sheet of paper and the samedelivered to one of the ities.

It will of course be understood that when the carriage carrying theimpression cylinder leaves one of the tables, the arm 45 at that endwill lower, and will of its own weight again project the arms 25inwardly to dispose the cam ends 26 beyond the inner edge of the tableextension or plate.
